Internet/DNS/XP/Web Browsing Problem

Situation:
We have travel laptops for our attorneys. They aren't tied to our network in any way, because the users have web based apps for whatever they need.

Recently our firm's site (home page) changed. Every PC that I have checked reflects the changes, inside and outside the network. The travel laptops, no matter where they are (connected to our network, connected to our network and bypassing our web filter, at a user's house, etc) will not display the new web page; it displays the old one. I have flushed DNS, cleared all temp files, offline files, history, and cookies, set the network connection to known good DNS servers, updated NIC drivers, have checked for viruses and spyware (nothing was found), and installed Firefox to rule out it being an IE 6 or 7 issue. Firefox gives me the same problem. I have erased all references to the page in the registry as well. As it is happening on more than one laptop and more than one browser type, I ruled out hardware and IE - seems like an OS issue?

have you tried resetting Internet explorer to default settings ?
also if this was rolled out to users using Group policy , when those machines are connected to your network try Gpupdate /force
finally if the problem persists, please post a hijack this log from one of the machines.

Are you running any type of Antivirus with some type of home page protection enabled that blocked all home page changes without notification. Checking your settings on that might help. There are a number of anti-spyware programs such as spybot search and destroy that will protect your homepage to prevent Browser Hijaking's. Any application such as this should allow you to disable the feature. I am just guessing, but since these are mobile machines i would assume you have some type of protection similar to this to prevent them from bringing some type of maliciously infected files into the network. It may explain why your stationary machines allowed the change if you do not have the same application installed on them.

If you have Spybot S&D installed for example this etting can be found under the following menu structure: click on "Tools", click on "IE TWEAKS" and uncheck "Lock IE startpage setting against user changes".

Also, Since you are having this problem with both browsers it is highly unlikely that hsi problem is being caused by file corruption. With regards to your previous post, Disabling Norton Anti-virus may simply not be enough to correctly determine whether it is cauising the problem. If the anti-virus client is changing the value of a registry key to achieve the effect of locking the web browsers homepages then disbaling the application is probably not changing the registry key back to a value that permits you to change your homepage. Try and determine if the anti-virus client even has the option to lock out a browsers homepage in the first place. If it does, track down the setting and check what it is set too.

Hijack this log looks ok , you can try to move IE Cache folder to a diferent location
Internet options>General>Browsing history>settings>move folder
once done , go to start menu
start>run>cleanmgr C:
choose all offline content and ok, you can then reset internet options.
>>Recently our firm's site (home page) changed
Just curious , did the company intranet URL change or is it the same ?
i.e. is the problem here wrong content or wrong Web address ??
